As shown in FIG. 3, 4, 5 and in conjunction with FIG. 2 , in the embodiment of the present application, the locking member 22 may include a fixing plate 221, a locking arm 222, a locking arm rotating shaft 2221, an unlocking arm 223, and an unlocking arm rotating shaft 2231.
The fixing plate 221 is mounted on the body of the automated guided vehicle, the locking arm rotating shaft 2221 and the unlocking arm rotating shaft 2231 are both located on the fixing plate 221, the locking arm 222 is connected to the fixing plate 221 through the locking arm rotating shaft 2221, and the locking arm 222 has a first rotational degree of freedom with the locking arm rotating shaft 2221 as an axis. The unlocking arm 223 is connected to the fixing plate 221 through the unlocking arm rotating shaft 2231, and the fixing arm 223 has a second rotational degree of freedom with the unlocking arm rotating shaft 2231. In one implementation, the unlocking arm rotating shaft 2231 is parallel to the locking arm rotating shaft 2221.
The locking arm 222 has a first locking flange 2222 and a second locking flange 2223, and a locking groove 2224 is formed between the first locking flange 2222 and the second locking flange 2223. When the locking hook 12 is locked on the locking member 22, the locking post 122 is located in the locking groove 2224, as shown in FIG. 2 .
The unlocking arm 223 has a first positioning flange 2232. When the locking hook 12 is locked on the locking member 22, the first positioning flange 2232 is located between the first locking flange 2222 and the second locking flange 2223, and the first positioning flange 2232 abuts against the first locking flange 2222, as shown in FIGS. 2 and 3 .
In an embodiment, a first torsion spring (not shown in the figure) is sleeved around the locking arm rotating shaft 2221, and the locking arm 222 has a rotation tendency in a direction from the first locking flange 2222 to the second locking flange 2223 via the locking groove 2224 under the action of the first torsion spring, i.e., the counterclockwise rotation tendency in FIGS. 3, 4 and 5 . A second torsion spring (not shown in the figure) is sleeved around the unlocking arm rotating shaft 2231, and the unlocking arm 223 has a rotation tendency opposite to that of the locking arm 222 under the action of the second torsion spring, i.e., a clockwise rotation tendency in FIGS. 3, 4 and 5 .
As shown in FIGS. 3, 4, and 5 , the fixing plate 221 further has a first stop flange 2211 and a second stop flange 2212. When the locking member 22 is unlocked from the locking hook 12, that is, when the locking member 22 is in the unlocked state, the locking arm 222 rotates under the action of the first torsion spring, so that when the locking groove 2224 faces the locking hook 12 (that is, the rotation position of the locking arm 222 in FIG. 4 ), an edge of the second locking flange 2223 on the locking arm 222 abuts against the first stop flange 2211, thereby preventing the locking arm 222 from continuing rotating.
As shown in FIG. 3 and FIG. 2 , the unlocking arm 223 further has a second positioning flange 2233. When the locking hook 12 is locked on the locking member 22, that is, when the locking member 22 is in the locking state, the second positioning flange 2233 abuts against the second stop flange 2212 under the action of the second torsion spring so as to prevent the unlocking arm 223 from continuing rotating, and further, the first positioning flange 2232 prevents the locking arm 222 from rotating towards the locking hook 12, to achieve the purpose of locking the locking hook 12.
As shown in FIGS. 2, 3, 4 and 5 , the unlocking arm 223 further has an unlocking handle 2234 that is located at an end of the unlocking arm 223 away from the unlocking arm rotating shaft 2231 to rotate in a direction (clockwise direction in FIGS. 3, 4 and 5 ) against the action of the second torsion spring under the pushing of the unlocking member 13, so that the unlocking handle 2234 can be disengaged with the locking groove 2224 from a side of the first locking flange 2222 when the first positioning flange 2232 is located between the first locking flange 2222 and the second locking flange 2223 and abuts against the first locking flange 2222.
For example, in the embodiments shown in FIGS. 3, 4 and 5 , the unlocking handle 2234 is located at an end of the unlocking arm 223 away from the unlocking arm rotating shaft 2231, and moves upward under the pushing of the unlocking member 13, so that the unlocking arm 223 rotates in the counterclockwise direction. Then, the first positioning flange 2232 shown in FIG. 3 is disengaged with the locking groove 2224 from a side of the first locking flange 2222. Further, the locking arm 222 rotates under the action of the first torsion spring, so that when the locking groove 2224 faces the locking hook 12, the edge of the second locking flange 2223 on the locking arm 222 just abuts against the first stop flange 2211, so as to prevent the locking arm 222 from continuing rotating, thereby forming the structural variation shown in FIG. 4 . Thereafter, as shown in FIG. 5 , the unlocking member 13 stops acting on the unlocking handle 2234, so that the unlocking arm 223 is returned to the original position under the action of the second torsion spring as shown in FIG. 3 .
As shown in FIG. 2 , in the embodiment of the present application, the unlocking member 13 includes an unlocking sleeve 131, an unlocking rod 132, and a return spring 133. The unlocking sleeve 131 is mounted on the battery assembly 1. For example, the battery assembly 1 may include a battery mounting plate 14, and the unlocking sleeve 131 may be mounted on a side of the battery mounting plate 14, which may be a part of 1, facing the battery 15.
